The only way to stop the program from restarting is to close the program. Use Recursion to Restart a Program import java.util.*; import java.util.Scanner; class Main { public static void addNumbers(int a, int b, int c) { Scanner sc = new Scanner(System.in); if (c == 0) { ...
比如即使要打印一下某个线程的stack trace,也必须要求所有的线程到达全局的safepoint才可以。 这就意味着操作的延迟,因为此时所有的线程都被stop了(也意味着大量的safepoint被JVM注入到我们的代码中,而“注入”这样的事情是我们在代码层面无法控制的)。 然而,有了ThreadLocal Handshake这个新功能后,就允许上面说的那些...
Most uses ofstopshould be replaced by code that simply modifies some variable to indicate that the target thread should stop running. The target thread should check this variable regularly, and return from its run method in an orderly fashion if the variable indicates that it is to stop running...

Stopwatch in Java Using System.nanoTime() We want to keep the stopwatch time as accurate as possible, and thus to do that, we use the System.nanotTime() class that returns the nanoseconds value that is the most precise value of the system timer. In the program, we create two classes...

若要從指令行啟動、停止或重新啟動伺服器,請分別使用dsadm start、dsadm stop與dsadm restart指令。 備註 – 若所停止及重新啟動的目錄伺服器實例,在依配置保存項目的記憶體中含有大量快取,這些快取將需要一段時間進行回存。在快取回存時,實例的回應速度將會減緩。
